INVERNESS, Fla. (AP) — Authorities say a woman died while scalloping in the Gulf of Mexico off the Florida coast.

A Citrus County Sheriff's Office news release says 66-year-old Ronda Mullin had been in the water for about 30 minutes Sunday morning when her family found her face down and unresponsive.

Officials say the family had boated from Bay Port to hunt for the wild saltwater clams. The woman's son performed CPR until the U.S. Coast Guard and state wildlife officers responded. The woman was later declared dead.

A medical examiner will determine the cause of death, which authorities say didn't appear to be suspicious.
